Effectiveness of helicopter versus ground ambulance services for interfacility transport

Background: Helicopters provide rapid interfacility transport, but the effect on patients is largely unknown, Methods: Patients requested to be transported between facilities by helicopter were followed prospectively to determine survival, disability, health status, and health care utilization. A total of 1,234 patients were transported by the primary aeromedical company; 153 patients were transported by ground and 25 patients were transported by other aeromedical services because of weather or unavailability of aircraft, Results: There were no differences at 30 days for survivors in disability, health status, or health care utilization, Nineteen percent of helicopter-transported patients died compared with 15% of those transported by ground (p = 0.21), Conclusion: The patients transported by helicopter did not have improved outcomes compared with patients transported by ground. These data argue against a large advantage of helicopters for interfacility transport. A randomized trial is needed to address these issues conclusively.
